There is also Processing code for generating png figures, available here (zip file, 863 kB). You will need the Apache Commons Math Java library for these exmaples. A version of the library that can be dropped into the "libraries" folder of your Processing sketch folder is available here.

Experiments

We conducted a series of experiments for this paper. This website provides details about these experiments not included in the paper for reasons of space or relevancy, as well as information for reproducibility.

A sample version of the experiment run in this paper (with slightly fewer stimuli for the purpose of convenience) is kept running here.

The difference between means, or the difference between the mean and the potential outcome

encoding

The type of encoding seen (0=bar,1=gradient,2=violin,5=modified box plot).

wording

The problem framing seen (0=election, 1=weather, 2=finance).

margin

The full length of the 95% confidence interval, *10

prediction

What the participants predicted. For one sample experiments, -1=the outcome will be lower than the potential, 1=the outcome will be higher. For two sample, -1=A will be higher, 1=B will be higher

confidence

How confident the participants were in their prediction, from 1=least, 7=most

outcome

How likely or severe an outcome the participants predicted. For the one sample test (1= the potential outcome is very unlikely, 7=the potential outcome is very likely). For two sample, -3=A will be overwhelmingly higher than B, 3=B will be overwhelmingly higher than A.
